Dr Nazir Ahmed Malik also have administrative experience of over 5 years as Head of the department, Associate Dean of Faculty and Director Academics. My PhD dissertation, published in an international W category journal, challenges the very foundation of the previous studies on grammatical aspects of intra-sentential code-switching since the 1970s. After rejecting the existing models of intra-sentential CS on theoretical and empirical grounds, I have presented a new perspective on intra-sentential code-switching in the light of Chomsky’s Minimalist Program. I happen to be the only PhD from a Pakistani university who has worked on the most recent developments made in contemporary linguistic theory i.e. Chomsky’s Phase Theory. My paper has been responded to by Jeff MacSwan, Professor University of Maryland, USA and he has dedicated a full paper A REPLY TO MALIK (published in W category journal) for the discussion on my new perspective.
